Dear Jim,

Thank you for your last letter telling me your recently news. I'd like to tell you something about our school sports meet. It was holding on Oct.20, which was a fine day. There were over 1,600 students and teachers attend it. Wang Lin, a student from my class won the 100-meter race. He finishes the race in 11.2 seconds and broke down the school record. They were all very excited. The sports meeting was great success. That was why we were all making every effort to our class honor. Although I was not one of the winner, I was proud of what we had done.

Looking forward to receiving your letter.

Yours,

Li Ping
